Methods and systems for generating long shutter frames

1. A method for generating long shutter frames for use in an electronic device, comprising: obtaining a plurality of frames; detecting a plurality of specific scenes respectively corresponding to the frames; assigning a plurality of weights respectively corresponding to the frames according to the specific scenes; and composing the frames according to the weights to generate a long shutter frame; wherein a plurality of determined characteristic points of the specific scenes are recorded in advance, and the frames are analyzed to obtain a plurality of current characteristic points, the current characteristic points are compared with the determined characteristic, points to know the specific scenes.

2. The method of claim 1 , wherein the frames are captured by an image capture unit with a same exposure time.

3. The method of claim 1 , wherein the frames are obtained from a video file.

4. The method of claim 1 , further comprising assigning a weight to respective regions of the frames, wherein the corresponded regions in the frames are composed based on the respective weights.

5. The method of claim 1 , further comprising performing an image pre-process on the frames before the frames are composed.

6. The method of claim 5 , wherein the image pre-process comprises an image stabilization process.

7. A system for generating long shutter frames for use in an electronic device, comprising: a storage device for storing a plurality of frames; and a processor for detecting a plurality of specific scenes respectively corresponding to the frames, assigning a weight to the frames according to the specific scenes, and composing the frames according to the weights to generate a long shutter frame; wherein a plurality of determined characteristic points of the specific scenes are recorded in advance, and the frames are analyzed to obtain a plurality of current characteristic points the current characteristic points are compared with the determined characteristic points to know the specific scenes.

8. The system of claim 7 , wherein the frames are captured by an image capture unit with a same exposure time.

9. The system of claim 7 , wherein the frames are obtained from a video file.

10. The system of claim 7 , wherein the processing unit further assigns a weight to respective regions of the frames, wherein the corresponded regions in the frames are composed based on the respective weights.

11. The system of claim 7 , wherein the processing unit further performs an image pre-process on the frames before the frames are composed.

12. The system of claim 11 , wherein the image pre-process comprises an image stabilization process.

13. A non-transitory machine-readable storage medium comprising a computer program, which, when executed, causes a device to perform a method for generating long shutter frames, wherein the method comprises: obtaining a plurality of frames; detecting a plurality of specific scenes respectively corresponding to the frames; assigning a plurality of weights respectively corresponding to the frames according to the specific scenes; and composing the frames according to the weights to generate a long shutter frame; wherein a plurality of determined characteristic points of the specific scenes are recorded in advance, and the frames are analyzed to obtain a plurality of current characteristic points, the current characteristic points are compared with the determined characteristic points to know the specific scenes.
